TRAP.,

SPECIFICATION forming' part of Letters Patent N o. 690,658, datedJanuary '7, 1902.

Application tiled March Z9, 1901; Serial No. 53,527. (No model.)

T0 ald whom t may concern:

Beit known that I, ROBERT G. MCAULEY, a citizen of the United States ofAmerica, and a resident of Pittsburg, county of Allegheny, State ofPennsylvania, have invented certain new and useful Improvements inTraps, of which the following is a specification, reference being had tothe accompanying drawings, forming part of this specification, in which=Figure 1 is a vertical sectional view of my improved gravity-trap. Fig.2 is a similar view showing the inner receptacle tilted and establishingsteam communication with the piston of the outlet-valve. Fig. 3 is aView in side elevation showing the application of the trap to asteam-line. Fig. 4 is a similar View showing its application to agas-line. Fig. 5 is a sectional detail view indicated by the line V V ofFig. 1. Fig. 6 is a partial perspective view of the tilting bucket. Fig.7 is ahorizontal cross-sectional view indicated by the line VII VII ofFig. 1.

My invention relates to the class of traps for collecting and disposingof water of condensation or other liquid accumulation; and it consistsin a trap adapted to receive liquid and to automatically empty by theoperation of a gravity-actuated interior bucket adapted to operate Valvemechanism whereby the eX- haust-op'ening is opened and closed, so as topermit a constant fluid-pressure to discharge the contents of the trap.

Referring now to the drawings, 2 represents the main shell of the trap,to the top 3 of which or at any other suitable location above thewater-line is connected a pipe 4, communicatin g with any constantsource of fluidpressure, as a steam or gas conductor. Connected with theshell 2, also at any convenient location above the water-line, is awatersupply or drain pipe 5, leading from any point in the line of pipeor vessel, as a separator 6, by which pipe waterof condensation iscarried to the interior of the trap, and for the purpose of delectingsuch water downwardly, so that it will not ilow directly into thebucket, I employ an arresting or deflecting shield 7, which shrouds theinner end of the opening, as shown.

Pivotally mounted, as by al hinge-joint 8, upon the inner side of thecase is a bucket 9,

vided for the piston and for stem 15.

located about centrally of the interior, the opening at the top of whichis preferably slanted downwardly toward one side, so that the water asit rises within the case around K the exterior of the bucket will flowover such lower side, and so fill the bucket. This bucket by reason ofits buoyancy will float upon the water and be maintained in an erectedposi- 6o tion until so iilled, when it will tip downwardly away from thehinge 8, as shown in Fig. 2, permitting the water to flow into it and tobe exhausted from the case down to the level of such lower edge of thebucket, as 65 shown in Fig. 2, in the manner I shall hereinafter morefully describe. For the purpose of facilitating the tilting action aweight 10 of suitable size may be attached to the inner upper edge ofthe bucket in any convenient 7o manner.

11 is an outlet-pipe extended down within the interior of the case andof the bucket to within a short distance of its bottom when raised, asshown in Fig. 1, and such outletpipe extends through the side of thecase and communicates with the upper side of a valvel chamber 12 above avertically-moving valve 13, located Within the case and adapted whenraised, as shown in Fig. 2, to establish com. 8e

munication from the interior of the bucket through pipe 11, valve-casel2, and itsroutletopening 14, which may lead to any'suitable point ofdischarge.

The valve-stem 15 of valve 13 is connected 85 at its lower end with apiston 16, which piston is normally held down, so as to seat the valve,by a spring 17, surrounding itsstem, the piston being mountedin acylinder 18, connected by suitable framework 19 with the 9o valve-case12, and proper packing being pro- It will be also noted that the area ofpiston 16 is greater. than that of valve 13 and its stem, thusfacilitating the opening of the valve. This construction of piston andvalve, the parts being in alinement and of simple'construction, by whichthe valve is opened directly against the pressure, so as togive freecommunication-to the atmosphere, is of great roo advantage in practicaloperation and is very simple in form. y p

By means of a port 20 through the bottom of the cylinder 18communication is established to a coupling 2l, the lower end of which ispreferably provided with a very small draining-port 22, and the couplingis connected with a pipe or other suitable connection 23, whichcommunicates, preferably through an angle-valve 24, with a port 25,leading to the interior of the ease. The inner end of this portterminates in a valve-seat 26, adapted to be closed by valve 27, whichvalve is formed or made on the end of a reciprocating stem 28, mountedin suitable bearings in the interior of the case.

The valve-stem 28 is provided with adjustable abutments 29, betweenwhich a bifurcated arm 30 is adapted to play and to move the valve-rodin or out by action against the abutments. This bifurcated arm isattached to and extends from the edge of the bucket 9, as shown, and inoperation when the bucket is buoyantly held up the valve will bemaintained closed, relieving pressure from piston 16 by cutting oif thesteam-supply, keeping the outlet-valve 13 seated, and allowing excesspressure or water of condensation to escape through port 22. When,however,-water in the interiorof the case has risen suiiciently high tooverflowinto the bucket and tip it by reason of the specific gravity ofthe bucket itself and its counterweight, the tipping action of thebucket and the corresponding movement of the bifurcated arm 30 upon thevalve 27 will open itA and establish pressure to piston 1G, raisingvalve 13, whereupon the pressure within the case through the pipe 4 willforce the fluid contents of the bucket outwardly through pipe ll untilthe level is lowered down to the lower end ofthe pipe 1l, when thebucket will oat upwardly, closing the valve and maintaining it so closeduntil the operation is again repeated.

The case 2 is provided at its lower point with a drain-cock 3l, by whichthe case may be emptied and accumulation of dirt or other foreignmaterial drained off, and a feature of advantage in the construction isthat all such accumulation of foreign material will settle to the bottomof the case, the clear Water only rising and flowing into the bucket, sothat no foreign material will pass through the pipe 11 to theoutlet-valve, wherebyitis constantly maintained in a clear and operativecondition.

The device may be used to drain any pipe or vessel where a pressure maybe had, and in its operation it is very efficient .and reliable,obviating the objections of other kinds of traps for this purpose, andit will be found by those accustomed to this class of mechanism to givecontinuous and satisfactory results.

The invention is very simple in construction, compact in size, andsymmetrical in form, economical to build, and not liable to get out oforder.

While the form I have shown is well adapted to the objects invview, itwill be understood that various changes and modifications may be made inits construction or design by the skilled mechanic without departingfrom my invention as embodied in the following claims.
